Description

NOUVEAU PANNEAU DECORATIF A BASE DE BOIS POUR L'AMENAGEMENTNEW DECORATIVE PANEL BASED ON WOOD FOR THE FITTING
INTERIEURINSIDE
La présente invention concerne un nouveau panneau décoratif à base de bois comportant une couche en aluminium pour l'aménagement intérieur, notamment de véhicules et en particulier pour l'aéronautique. Dans ce dernier domaine, on recourt actuellement pour l'aménagement intérieur des cabines des jets d'affaire ou des avions de ligne commerciaux à des panneaux stratifiés en bois à trois plis ou couches, comportant une couche de placage bois externe, une couche centrale en bois et une couche de contreplacage en bois, également appelée contre- face. L'orientation des fibres du bois de la couche de placage et de la couche de contreplacage est identique et perpendiculaire à celle de la couche médiane.The present invention relates to a new wood-based decorative panel comprising an aluminum layer for interior design, including vehicles and in particular for aeronautics. In the latter area, the interior design of booths for business jets or commercial airliners is based on laminated wood panels with three plies or layers, with a layer of external wood veneer, a central layer of wood and a layer of wood plywood, also called counter-face. The orientation of the wood fibers of the plating layer and the plywood layer is identical and perpendicular to that of the middle layer.
Ces panneaux décoratifs connus sont utilisés pour l'habillage des meubles tels que des banques ou des bars et pour couvrir les parois murales. Comme tous les matériaux employés à bord de véhicules aéronautiques, ces panneaux décoratifs répondent aux normes très strictes en vigueur et notamment aux normes de tenue au feu et de dégagement de chaleur.These known decorative panels are used for dressing furniture such as banks or bars and to cover the walls. Like all the materials used in aeronautical vehicles, these decorative panels meet the very strict standards in force and in particular the standards of fire resistance and heat release.
Toutefois, ces panneaux décoratifs connus représentent un certain poids et l'Homme du Métier sait bien que tout gain en ce domaine est important dans l'aéronautique. A cet égard,- on pourra se référer au brevet français FR 2.563.153 qui divulgue un panneau composite, notamment destiné au mobilier d'avion, formé d'un panneau du type nid d'abeille recouvert d'un placage de bois.However, these known decorative panels represent a certain weight and the skilled person knows that any gain in this area is important in the aeronautics. In this regard, - we can refer to the French patent FR 2,563,153 which discloses a composite panel, in particular for aircraft furniture, formed of a honeycomb panel covered with a wood veneer.
En outre, ces panneaux décoratifs connus, tout comme celui du brevet FR 2.563.153, ne sont pas suffisamment souples, flexibles, pour être employés tels quels dans toutes les parties des aéroplanes. En effet, lorsque l'on est confronté à des sections à recouvrir présentant des rayons de courbures étroits (inférieurs à 150 mm) , ces panneaux connus constitués de trois couches en bois d'épaisseur de 0,6 mm chacune, ne peuvent être employés. La solution actuellement utilisée est une couche de contreplaqué collée sur un intissé en cellulose. Or, ce dernier produit n' est pas agréé vis à vis des normes de tenue au feu ou de dégagement de chaleur.In addition, these known decorative panels, like that of FR 2,563,153, are not flexible enough, flexible, to be used as such in all parts of airplanes. Indeed, when faced with sections to cover with narrow radii of curvature (less than 150 mm), these known panels consist of three layers of wood thickness of 0.6 mm each, can not be used . The solution currently used is a layer of plywood stuck on a non-woven cellulose. However, the latter product is not approved with respect to standards of fire resistance or heat release.
Par ailleurs, on connaît des panneaux stratifiés associant des couches de bois et d'aluminium. On pourra se référer par exemple, aux brevets anglais GB 2.358.372 etFurthermore, there are known laminated panels combining layers of wood and aluminum. For example, reference may be made to British Patents GB 2 358 372 and
GB 2.306.389, au brevet américain US 3.708.385 ou au brevet allemand DE 198.29.057. Ces brevets décrivent toutefois des panneaux rigides, inadaptés à l'utilisation visée d'habillage de meubles ou de recouvrement de parois non planes.GB 2,306,389, US Pat. No. 3,708,385 or German Patent DE 198.29.057. These patents, however, describe rigid panels, unsuited to the intended use of furniture covering or covering non-flat walls.
La présente invention vise donc à proposer un produit de remplacement de ces panneaux décoratifs en stratifié de trois couches en bois qui sont aujourd'hui employés dans 1' aéronautique .The present invention therefore aims at proposing a replacement product for these decorative wood laminate panels of three layers which are today used in aeronautics.
Le produit selon l'invention est donc plus léger, conforme aux normes en vigueur - spécialement vis à vis de la tenue au feu - et présente une souplesse, une flexibilité, permettant de l'employer sur la totalité des surfaces à recouvrir.The product according to the invention is therefore lighter, in compliance with the standards in force - especially with respect to fire resistance - and has flexibility, flexibility, allowing it to be used on all the surfaces to be covered.
En outre, le produit selon l'invention présente une planéité optimale, c'est-à-dire qu'il résiste à tout gauchissement lors de la pose et dans le temps.In addition, the product according to the invention has an optimum flatness, that is to say, it resists any warping during installation and over time.
A cet égard, il est proposé un nouveau panneau décoratif stratifié flexible à base de bois comportant au plus trois couches dont une en aluminium, remarquable en ce qu'il comprend au moins deux couches, une couche en bois, dite face de parement, dont l'épaisseur est comprise entre 0,6 et 1 mm et une couche en aluminium constituée par une feuille d'aluminium dont l'épaisseur est comprise entre 60 et 90 microns.In this regard, there is proposed a new flexible laminate wood-based decorative panel having at most three layers including one aluminum, remarkable in that it comprises at least two layers, a layer of wood, said facing face, of which the thickness is between 0.6 and 1 mm and an aluminum layer consisting of an aluminum foil whose thickness is between 60 and 90 microns.
Dans une première variante, ce panneau décoratif est donc un stratifié bicouche, bois/aluminium.In a first variant, this decorative panel is a laminate bilayer, wood / aluminum.
Dans une seconde variante, le panneau décoratif est un stratifié tricouche, comprenant une dernière couche dite contre-face, à base de bois.In a second variant, the decorative panel is a three-layer laminate, comprising a last layer called counter-face, based on wood.
De fait, le déposant s'est aperçu, après de nombreux essais sur différentes combinaisons de matériaux et de structures à deux ou trois couches, que de manière fort surprenante, ce produit associant du bois et de l'aluminium remplissait l'ensemble des conditions nécessaires à sa mise en œuvre dans le domaine de l'aéronautique, avec des performance supérieures à celles des panneaux décoratifs connus .In fact, the applicant found, after many attempts on different combinations of materials and structures with two or three layers, that surprisingly, this product combining wood and aluminum fulfilled all the conditions necessary for its implementation in the field of aeronautics, with performance superior to that of known decorative panels.
Ce produit, dans sa version à deux ou trois couches, a passé avec succès les test de conformité aux normes de tenue au feu et la version bicouche répond aux normes de dégagement de chaleur.This product, in its two- or three-layer version, has successfully passed the fire performance test and the bilayer version meets the heat release standards.
Par rapport aux panneaux connus à trois plis en bois, le gain de poids est d'environ 20 à 30 % par mètre carré dans la version trois couches, selon les essences employées, et bien entendu d'au moins 50 % en version deux couches. En outre, la flexibilité du produit facilite son cintrage et autorise son utilisation sur des surfaces avec des rayons de courbure inférieurs à 150 mm, jusqu'à 25 mm sous certaines conditions de préparation, par exemple en mouillant la face de parement et en ponçant la contre-face. Le panneau décoratif selon l'invention permet donc de décorer l'ensemble d'une cabine d'avion avec un produit agréé vis à vis de la tenue au feu.Compared to the known three-ply wood panels, the weight gain is about 20 to 30% per square meter in the three-layer version, depending on the species used, and of course at least 50% in two-layer version . In addition, the flexibility of the product facilitates its bending and allows its use on surfaces with radii of curvature less than 150 mm, up to 25 mm under certain conditions of preparation, for example by wetting the face of the facing and sanding the against face. The decorative panel according to the invention thus makes it possible to decorate the assembly of an aircraft cabin with an approved product with respect to the fire resistance.
Par rapport à la version bicouche, la version tricouche présente une planéité meilleure, du fait de sa stratification symétrique ; elle présente donc un plus grand confort d'utilisation. En outre, sa plus grande épaisseur permet de mieux absorber les irrégularités du support de fixation du panneau et ainsi d' obtenir une surface bien lisse, après préparation. Cette même épaisseur autorise de surcroît l'usinage de rainures décoratives sans risque d'atteindre le support de fixation.Compared to the bilayer version, the three-layer version has a better flatness due to its symmetrical stratification; it therefore presents a greater comfort of use. In addition, its greater thickness makes it possible to better absorb the irregularities of the fixing support of the panel and thus to obtain a smooth surface, after preparation. This same thickness also allows the machining of decorative grooves without risk of reaching the mounting bracket.
On comprend bien que ce panneau décoratif pourra, bien entendu, être utilisé pour toute autre application de panneau décoratif, par exemple pour l'équipement de bateaux, de wagons de chemin de fer ou encore dans les immeubles de grande hauteur, en adaptant les épaisseurs des couches de matériaux au degré de flexibilité souhaité. En vue d'une utilisation dans l'aéronautique et selon une autre caractéristique de l'invention, les deux couches à base de bois du panneau décoratif (la face et la contre- face) ont de préférence une épaisseur de 0,6 mm. Dans le cadre de l'invention, ces deux couches pourront avoir une épaisseur comprise entre 0,6 et 1 mm.It is understandable that this decorative panel can, of course, be used for any other application of decorative panel, for example for the equipment of boats, railroad cars or in high-rise buildings, adapting the thicknesses layers of materials with the desired degree of flexibility. For use in aeronautics and according to another characteristic of the invention, the two wood-based layers of the decorative panel (the face and the counterface) preferably have a thickness of 0.6 mm. In the context of the invention, these two layers may have a thickness of between 0.6 and 1 mm.
L'épaisseur de la couche centrale en aluminium, constituée par une feuille plane, sera comprise entre 60 et 90 microns. De préférence, on utilisera une feuille d'une épaisseur proche de 70 microns, avec les marges de tolérance appliquées habituellement lors de la fabrication de ces feuilles d'aluminium.The thickness of the central aluminum layer consisting of a flat sheet, will be between 60 and 90 microns. Preferably, a sheet with a thickness close to 70 microns will be used, with the margins of tolerance normally applied during the manufacture of these aluminum foils.
L'assemblage des trois couches entre elles se fait selon des techniques classiques de collage et de pressage à chaud, connues de l'Homme du Métier afin d'obtenir un panneau stratifié. On pourra par exemple utiliser une colle du type phénolique thermodurcissable ou du type polyamide thermoplastique. Les paramètres de pressage (pression, température) à mettre en œuvre sont aisément déterminables par l'Homme du Métier, en fonction de la colle et de la nature des matériaux employés (essence de bois, fabriquant d'aluminium) ainsi que de la destination du stratifié. En effet, si l'on souhaite incorporer des placages en loupe ou de type marqueterie, pour ne pas abîmer les motifs du bois on effectuera l'assemblage à une pression relativement basse (inférieure à 10 kg/m2) en comparaison à celle appliquée pour des placages standards.The assembly of the three layers together is done according to conventional techniques of gluing and hot pressing, known to those skilled in the art to obtain a laminated panel. For example, it is possible to use a glue of the phenolic thermosetting type or of the thermoplastic polyamide type. The pressing parameters (pressure, temperature) to be implemented are easily determinable by the skilled person, depending on the glue and the nature of the materials used (wood species, aluminum manufacturer) and the destination laminate. In fact, if it is desired to incorporate veneers with magnifying glass or inlay type, in order not to damage the wood patterns, the assembly will be carried out at a relatively low pressure (less than 10 kg / m 2 ) in comparison with that applied. for standard veneers.
L'Homme du Métier déterminera, pour chaque type d'association colle/bois/aluminium, les paramètres optimaux de pressage permettant la cohésion du stratifié et notamment le maintien de la liaison bois-aluminium lors des déformations subies par le panneau quand on procède à sa pose .The person skilled in the art will determine, for each type of glue / wood / aluminum combination, the optimal pressing parameters allowing the laminate to cohere and in particular the maintenance of the wood-aluminum bond during the deformations undergone by the panel when his pose.
En outre, la face de parement et la contre-face sont de même nature que celles des panneaux décoratifs entièrement en bois, utilisés jusqu'ici. Elles pourront également être traitées avec des solutions ignifugeantes et/ou des vernis retardateurs de flamme, comme cela est habituellement pratiqué. On comprend bien la qualification « à base de bois » du panneau décoratif selon l'invention puisque ce matériau représente plus de la moitié en poids des constituants. Dans une variante de l'invention, la contre-face est obtenue dans du bois déroulé en lieu et place du traditionnel placage. En effet, lors de l'assemblage du panneau les nervures du placage de la contre-face risquent de ressortir en surimpression sur la face de parement, la feuille médiane d'aluminium n'empêchant pas cette surimpression. L'utilisation du bois déroulé évite ce phénomène. On pourra avantageusement utiliser du bois d'Okoumé à cette fin.In addition, the facing face and the cons-face are of the same nature as those decorative panels made entirely of wood, used until now. They can also be treated with flame retardant solutions and / or flame retardant varnishes, as is usually practiced. We understand the qualification "wood based" decorative panel according to the invention since this material is more than half by weight of the constituents. In a variant of the invention, the counter-face is obtained in unrolled wood instead of the traditional veneer. Indeed, during the assembly of the panel the ribs of the veneer of the counter-face may emerge superimposed on the facing face, the middle sheet of aluminum does not prevent this overprint. The use of unwrapped wood avoids this phenomenon. Okoumé wood may advantageously be used for this purpose.
Selon une autre caractéristique de l'invention, on pourra avantageusement augmenter encore la flexibilité du panneau décoratif et ainsi réduire encore la valeur du rayon de courbure limite du produit, en procédant à un défibrage par microfractures du placage en bois, selon les techniques bien connues de l'Homme de l'Art. Enfin, il va de soi que le panneau décoratif à base de bois selon l'invention peut être utilisé pour tout type d'aménagement intérieur et que les exemples que l'on vient de donner ne sont que des illustrations particulières, en aucun cas limitatives des domaines de l'invention. According to another characteristic of the invention, the flexibility of the decorative panel can be advantageously further increased and thus further reduce the value of the limit radius of curvature of the product, by performing a defibration by microfractures of the wood veneer, according to well-known techniques. of the Man of Art. Finally, it goes without saying that the wood-based decorative panel according to the invention can be used for any type of interior layout and that the examples that have just been given are only particular illustrations, in no way limiting. areas of the invention.
